JW Pet Fusion Check Valve

The Fusion Check Valve is a duck bill styled valve that helps prevent backflow. This accessory is a useful tool when running Anchor Bubblers, ActivAir Ornaments, Anchorstone Sand Airstones, and Aircore Sand Airstones to prevent water from back flowing into the Fusion Air Pump. The Fusion Check Valve is a great item for any aquatic add-on sales.
